HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 349,991, datedSeptember 28, 1886.

Serial No. 193,230. (No model.)

To all whom, it may concern:

Beit known that I, EDWARD E. GOLD, a citizen of the United States,residing at New York city, county and State of New York, have inventedcertain new and useful Improvements in Hose-Couplings, of which thefollowing is a specification.

My invention is more especially designed for a steam hosecoupling to beused between the ends of railway-cars in a train, so as to connect theheating-pipe of one ear to that ot' the next car or to the engine; andmy invention relates to that class of couplings formed of two crankedbends or elbows fitting end to end lin the form of a bisected S, theends engaging together by a partial rotary motion, and a form ofbayonctfastening.

My improvement consists in certain details of construction which renderthe coupling Very strong, simple, and efficient, as hereinafter fullyset forth.

In the drawings annexed, Figure l presents a side elevation of myimproved coupling` in the position assumed when looked together toconnect the hose from car to car. Fig. 2 isa longitudinal section orsectional plan of the locked coupling. Fig. 3 is an exterior' plan ofthe two halves separated. Fig. 4 is an elevation ofthe two separatedhalves viewed in the direction of their meeting laces.

In the drawings, A indicates what may be 4termed the female half of thecoupling, and B the male half. Fach section is a simple tubular casting,straight at its outer end and formed with a conical and ribbed shank, aI), respectively, to connect with the hose and curved into the form of acranked bend or elbow, c d, respectively, at their inner meeting ends,which junction together in the form of an S-trap, as seen best in Figs.2 and 3. The male half B has a circular' flange, e, at its junction end,with two notches, f f, in its pe riphery at diametrically-oppositesides, as shown in Figs. 1, 3, and 4. The top or outer surface of theflange is formed with two inelines, g, or sections ofscrew-threadsinclining in opposite directions from said notches, asshown best in Fig. 3, while the under or junction surface, 7i, ot' thefiange is level and smooth, as seen best in Figs. 2, 3, and 4. Now, thefemale section A is formed with a rimmed cup or socket, Il', to receivethe flange c, as seen in Figs. 'l and 2. The socket lu has a smooth andlevel base, 1', as seen in Fig. 2, on which is placed a packingnvasher,t', against which the flange c lits when the sections are coupledtogether, as seen in Fig. 2. The base fi of the socket has a centralopening in line with the bore or passage of the sections, to allow afree passage to the Steam when the two sections are coupled, and in thisopening is screwed a small shouldered screw-thimble, m, (see Figs. 2 and4,) whose shoulder bears firmly on the washer i, and thus holdsitsccurely in place. The bore or interior of the thimble m is providedwith one or more notches or ribs, m', to afford grasp to a wrench ortool for screwing the thimble in and out, as will be understood. Now,referring again to the several figures, it will be seen that the socketend of the section A is formed with two projections, n n, which extendradially inward at diametrically-oppo site sides of the socket-rim 7.',and above the same, as well shown in the drawings, which projectionscorrespond with the notches j" j' in the flange c. It may now be seen,referring to Fig. 1, that to couple the sections together it is onlynecessary to insert the fianged male section A in the socket in suchposit-ion that the notches f coincide with the projections n n, and tothen press the flange against the washer t, and partly revolve theflange on the socket-section. This partial revolution will cause theinclines g r/ on the top of the flange to pass under the projections anwith a powerful wedging or screw action, which will force the flange cfirmly against the washer z', and thus render the joint of the couplingperfectly secure and steam-tight.

It will be readily seen on reference to Fig. l that in order to couplethe sections, as described, when attached to the hose between themeeting ends of the cars, it is only nece?.- sary to raise up thesections in an inclined position at or nearly at right angles to eachother, as shown by dotted lines, in which position the notches f andprojections a will match, and then by simplyinclining or bending thesections downward, toggle-like, as shown by full lines, the flange ot'one section will partly rotate in the socket of the other, and the twowill thereby become clamped together steam -tight with a most powerfulme- IfO chanical action, combining the screw and toggle, which insuresabsolute tightness, and is yet performed by a most simple and easy etfort of the hand, no wrench or other tool being-required. It will befurther seen on ret'- erence to the full lines in Fig. l that when thuscoupled the sections assume a bent or drooping position, correspondingto thc natural droop of the hose' between the cars, so that the naturaldroop orgravitation of the hose and coupling only tends to still furthertighten the coupling. On the other hand, to uncouple lthe parts, it isonly necessary to lift and bend the coupling in an upward direction, asshown by dotted lines, which will revolve the flange so that the notchescoincide with the projections and allow the parts to separate by asimple and easy motion.

The washer i is preferably niade of'softvulcanizablerubber-suchas knownas Jenkinss packing, but any othersuitablematerial may be used. Thefaces 7L of flange e and the top ofthe base 1" might be ground to fittogether, and the forni of these laces might be conical in the manner ofvalve and seat; but the flat,

only mechanical work required on the sections after being east is toturn off the bottom and sides ofthe socket 7c and the face h of theflange e, and to tap the opening to receive the thirnble m. The inclinesg will generally need only alittle iiling,ivllile thebearingfaees oftheprojections n will be iinished off in the act of turning out the socket7c, as will be readilyy combination oli' the section B, havingthebearing-flange c, with the section A, having the socket 7.x, with theWasher t' and retainingthinible m, substantially as herein set forth.

2. In a two-part biseeted coupling, the coinbination of thesocketsection A, with Washer fi, thilnblc mi, and projections lt, withthe section B,having theseatingilange e,with notches j' and inclines g,substantially as shown and described.
